the blinkenlights have spoken

A busy day sorting out various things at work. One of our big GPU systems had switched itself off during the night. On the way home I visited the machine room (again) to take a video of the 7 segment display as requested by the tech support. A web search suggests there is a problem with the CPU tray. Ah well, I guess we will get a visit from the technicians. Went to a nice talk on early flower photography and how it changed between the early 20th century and the 1930s.
